Source/cmCTest.cxx: Add missing newline (#12538)

In the log entry, the newline is missing. The output without the newline
character is a bit strange, like

 SetCTestConfigurationFromCMakeVariable:MemoryCheckCommand:CTEST_MEMORYCHECK_COMMANDSetCTestConfiguration:MemoryCheckCommand:/usr/bin/valgrind

Instead of

 SetCTestConfigurationFromCMakeVariable:MemoryCheckCommand:CTEST_MEMORYCHECK_COMMAND
 SetCTestConfiguration:MemoryCheckCommand:/usr/bin/valgrind

This patch changes this to add a newline.
